Science - Predicting.

Today at Science we did an experiment, but before we did the experiment on a document we had to predict what was going to happen. Our teachers showed us the reactants (vinegar and baking soda.) We also had to predict what the product and the chemical reaction was going to be.
My guess spot on since I've seen these types of experiments before.

Chemical Reaction - Elephant Toothpaste

Today for Science we did an experiment called Elephant Toothpaste.
This Google Drawing shows what we did.
The hardest part as usual was to make sure the labels go in the right place, like Product, Reactant.

Science

In Science we are learning about Changes.
Changes happens when we mix or combine two different reactants (substances) together. When this happens a chemical reaction takes place. Our teacher got four ingredients, baking soda, baking powder, water and vinegar. He mixed the baking soda and baking powder together..the  product was gas (Carbon Dioxide) . Then he mixed baking powder and vinegar and it made noises such as, fizzing and pooping.

Science - Change

I am starting to learn about Science and change. This is what I found out today. What new information can someone tell me?
